Yes we do have a 48" Rumford in operation in the showroom. We put it
in about a year ago, and we actually burn it every day, the whole day.

I do have to say the fireplace does help sell its self. It is like
having a campfire in the office with 4' flames. I would caution though about the prices though. Around here we see most masons charging ~ $10 - $15,000 (with materials).
